BEIJING (Reuters) - China's anti-graft watchdog has discovered 37 kg (82 lbs) of gold, documents for 68 houses and 120 million yuan ($19.6 million) in cash in the home of a Communist Party official who is being investigated for corruption, state media said.

The amount that was discovered in the home of Ma Chaoqun, who was the former manager of the Beidaihe Water Supply Corporation, was so large that state news agency Xinhua called it "shocking".
